4 Chemistry questions? Help please!?

"K" is:

The temperature in degrees kelvin

The molar constant

The rate constant

The gas constant

The magnitude of the specific rate constant depends on the conditions at which the reaction is conducted. One factor that doesn't affect the rate is:

light

production of unwanted products

solubility issues

change in concentration

The specific rate constant is part of the rate law. The rate law is an expression relating:

the rate of a reaction to the concentration of reactants

the rate of a reaction to the temperature

the rate of a reaction to the pressure

the rate of the reaction to the humidity

"K" is large if reactions react quickly together: TRUE OR FALSE?

    1) K is the rate constant at Equilibrium.

    2)

    light-can act as an oxidation as in the case of Vitamin C so thats right

    production of unwanted products- this always happens so it doesnt affect the rate

    soulbitlity issues-causes problems dissolving substances basically and can result in a slower rate

    concentration-will change rate

    3) the rate of a rxn to the concentration of reactants, although pressure is also acceptable answer.

    4.) Not exactly, a K only means how much reacted (dissociated) a K=1 means 100% dissociation

    so False.

    a million. uncertain with offered products. 2. odor flammability density 3. Wakif if solids are consistently denser then how come they are able to drift in beverages. Like timber in a lake. 4. chilly water is extra dense because of fact while some thing gets chilly in contracts putting the comparable volume of cloth in much less area. (except the chilly water is ice because of fact ice's atoms repel one yet another in assessment to maximum supplies thereby getting much less dense)
